"hairy palms" and Insomina w/ Concerta | ADHD Information

My daughter has been on Concerta for almost 1 yr. She takes 36mg daily. No
weekends, no summer. She has had no side effects until last month. Last
month she had an operation that unblocked an aorta. Since then she has
been complaining about insomnia and feeling like there is hair or spider
webs on her palms.

Any clues? The ped. and cadiologist do not think the increased blood flow
and the symptoms are related. I am not too sure.
